Title: Improvements in carburetters for internal combustion engines
IPC: F02M17/14
Filed: 1922-07-05
Abstract: 182,801. Joly, V. July 7, 1921, [Convention date]. Spray carburettors. -The supply of mixture and of additional air is regulated by a member actuated by the engine suction. The casing 1 comprises a cylinder 5 in which slides a piston 4, the tubular rod 2 of which controls the mixture and carries an additional air valve 3. The member 2 is ported at 15 and slides over a central member 10, which is ported at 14, carries a fuel nozzle 13 at a constricted part of a chamber 12 therein, and is adjustable by means of a lever 11 for altitude and temperature changes. The spaces A, C above and below the piston 4 com. municate through conduits 6, 7 respectively with the chambers B, D on the air inlet and engine sides respectively of the throttle valve 8. When the valve 8 is closed, the piston 4 and member 2 are lowered and the ports 15 and valve 3 are closed. As the valve 8 is opened the suction effects on the upper and lower faces of the piston 4 become more nearly equal, and the piston and member 2 are raised by the atmospheric thrust on the valve 3 to admit more mixture and additional air. If the member 2 rises too far, suction is reduced in the region B and space A and the greater suction through conduit 7 causes the piston 4 and member 2 to descend. The same effect is produced each time the valve 8 is moved or when the engine suction varies. The chamber 12 may be supplied with hot air.

Title: Apparatus for preventing the withdrawal of current from the mains side of a consumers current meter
IPC: G01R11/24
Filed: 1930-06-18
Abstract: 357,221. Supply meters. FRESCHEVILLE, G. DE, Subotica, Belgrade, Jugoslavia. June 18, 1930, No. 18603. Convention date, June 18, 1929. [Class 37.] The circuit is broken and an alarm given when current is taken from the supply conductors between the meter and the mains. Two electromagnets A, B are connected as shown so that they are normallv in series with each other and with the series winding of the supply meter 3<1> through a switch K. Current supplied to the consumer's circuit P passes through the winding of both electromagnets A, B, which are so arranged that their magnetic fields neutralize one another at the position occupied by an armature m. Current passing through a circuit P<1>, tapped from the mains side of the meter, passes through the winding of the electromagnet A only, causing the armature m to be attached thereto and thereby close the circuit of an electromagnet R. This releases the switch K, which is moved by a spring d, opening the main circuit and closing the circuit of a signal lamp L. The coils of the electromagnets A, B are adjustable axially and the cores are adjustable within the coils, for example by being screwed at their outer ends and provided with nuts. An adjustable spring (not shown) acts on the part carrying the armature m to vary the sensitivity.

Title: Manufacture of dyestuffs of the polymethine series
IPC: C09B23/06
Filed: 1928-06-27
Abstract: 321,155. Imray, O. Y., (Soc. of Chemical Industry in Basle). June 27, 1928. Cyclammonium polymethine compounds.-Dyestuffs are obtained by oxidizing, in a medium which is not alkaline, a condensation product produced : (1) by the action of formaldehyde (1 mol.) upon a methylene base of a cyclammonium salt having a reactive methyl group in the alphaposition (2 mols.), or (2) by removal of acid, by treatment with alkali, from the product produced from formaldehyde (1 mol.) and a cyclammonium salt having a reactive methyl group in the aposition (2 mols.). In examples, formaldehyde is condensed with 1 : 3 : 3-trimethyl-2-methyleneindolin in alcoholic solution, and the product, dissolved in benzene, oxidized by means of benzoquinone in the presence of acetic acid. The resulting addition product of 1 3 : 3 : 1<1> : 3'- : 3<1>- hexamethylstreptomonovinylene-2 : 2<1>-indocyanineacetate with hydroquinone may be treated with alkali to give the free base, which yields a hydrochlcride on dissolution in dilute hydrochloric acid; (2) lead peroxide is used for oxidation of the same condensation product; (3) methylenedi-quinaldine iodomethylate, prepared from formaldehyde (1 mol.) and quinaldineiodomethylate (2 mols.), in the presence of a small quantity of piperidine, is treated with 30 per cent caustic soda at 70-80‹ C. and the base, dissolved in chloroform, oxidized by means of quinone in the presence of acetic acid. The product is probably an addition product of hydroquinone and 1 : 1<1>-dimethylstreptomonovinylene - 2 : 2<1>- quinocyanineacetate. Methylene bases of trimethylindoleninium salts derived from o- and p-toluidine or other substitution products or homologues of aniline or of a- or #-naphthylamine may also be condensed with formaldehyde and then oxidized. The dyestuffs from o- and p-toluidine yield pure bluish red tints on cotton mordanted with tannin while the dyestuffs from # -naphthylamine dye this material violet tints having a reddish fluorescence. Instead of quinone, derivatives of quinone, e.g. 2 : 6-dichlorquinone, or nitroso compounds, metallic oxides and salts, oxygen or air may be used. Formic, propionic, benzoic, sulphuric and hydrochloric acids are mentioned as acids that may be used in place of acetic acid.

Abstract: 942,592. Seaming non-metallic sheet material. TELEPHONE CABLES Ltd. May 11, 1962 [May 24, 1961], No. 18784/61. Heading B5K. [Also in Division H2] A joint is formed between facing surfaces of two thermoplastic members 1, 3 by interposing an electrical heater 5 of coherent open-work form between the two surfaces, fusing the material at the interface between the surfaces by the heater 5 and then withdrawing the heater with a motion which is agitated during at least an early part of the withdrawal. To join two lengths of polythene-sheathed cable, the sheath is cut back to expose the conductors 2 which are joined and a polythene sleeve 4 previously applied over the cable is slipped over the joint. A polythene collar 3 may be provided for each end of the sleeve 4. To join the collar 3 to the sheath 1 the heater 5 is interposed therebetween and a tape 6 is applied under tension to the outside of the collar. The heater 5, Fig. 2, comprises a stainless steel mesh strip cut on the bias and has an unstretched diameter slightly less than that of the sheath 1. A carrier 9 carries the heater 5 by strips or pins 8 and connecting leads 7 secured thereto. The tape 6 may comprise a length of silicon elastomer or neoprene tape having a bias cut stainless steel heater 10 secured thereto and being of such a length that its ends overlap. The inner end of the tape 6 is preferably tapered. The collar 3 is first softened at a temperature between 60  and 85 C. by the heater 10 and the heater 5 heats the material at the interface to a temperature between 150 and 180 C. to form the joint. The heater 5 is withdrawn by combining both axial and to-and-fro angular movement along the cable axis, the tape 6 still applying pressure. The heater 5 is cut from the cable and the carrier 9 and the tape 6 are removed. Similarly, the sleeve 4 is joined to the collar 3 at A. The heater 10 may be dispensed with and preliminary softening may be obtained by initially running the heater 5 at a low current. In a modification, Fig. 5, the tape 6 is wound without tension and a closed, rectangular crosssection pneumatic tube 12 is applied around the tape 6 and is constrained against movement by U-section members 13 articulated together. Pneumatic pressure is admitted through a port 14 and the tube ends overlap at 12<SP>1</SP>.

Patent GB-188718-A (GB)
Abstract: 188,718. Siemens Bros. & Co., Ltd., and Christian, D. A. July 14, 1921. Automatic exchange systems.-In a system of the hind in which a faulty line is connected to a special out-of-order circuit provided with a ring- ing-responsive relay which, in the event of an attempted connection with the faulty line, effects the operation of the ringing-cut-off relay, the circuit of the ringing-responsive relay is made dependent upon the electrical condition of one of the speaking leads in such a way that the circuit is opened when direct ground is removed from this speaking lead by the operation of the ringing- cut-off relay. The disconnection of the ringing- responsive relay is effected by a further relay which also controls the transmission of a special tone signal to the calling subscriber. In the system shown in Figs. 1 and 2, the faulty line has been disconnected at the main distributing frame, the line and exchange branches being connected to plugs 7, 5 respectively. The plug 5 is inserted in a jack EJ leading to a " plugging- up " circuit shown in Fig. 2. A branch 8 controlled by switch members 9, 10 leads to a jack LJ into which the plug 7 may be inserted if a through connection between the line and exchange branches is desired. When a connector LW has been set upon the terminals leading to the faulty line, test relay P energizes in series with the cut-off relay T of the called-subscribers' preliminary selector VW and ringing current is supplied from the generator 6 over the circuit TR, tr<3>, p<3>, b<1>, 4, 14, S. Relay S responds to the ringing current and closes at its contact s<1>, a ground connection for the ringing-cut-off relay TR which energizes and disconnects the generator 6, connects through the a- and b-leads at contacts tr<2>. tr<3> and breaks a ground connection at the back contact tr<2> over which the relay LR has been previously short-circuited. Relay LR energizes in a circuit 13, w<1>, 15, disconnects the relay S, and causes a special tone signal from the transformer 11 to be transmitted to the calling subscriber. When the subscriber hangs up, relays P, T fall back, and an earth connection at the back contact t<2> short-circuits relay LR which de-energizes and restores the " plugging-up " circuit to normal. Feed relay Y at the group selector IGW is connected in parallel with relay LR as soon as relay TR energizes, but is of such high resistance that it does not energize, thus preventing the metering which, in the case of a successful call, it would have effected. In a modification, the battery 15 is connected to the resistance w<1> over additional front contacts of relays LR, S arranged in parallel.

Abstract: 987,571. Sausage skin shirring UNION CARBIDE CORPORATION May 25, 1961 [June 7, 1960], No. 18990/61. Heading A2B. Sausage casing is shirred in a continuous three-stage process by (i) passing a measured length of inflated cellulosic casing through a shirring head into a mandrel and compressing the loosely shirred casing by a predetermined amount (e.g. to 1/25th of its original length) by advancing the shirring head along the mandrel, (ii) returning the shirring head, separating the shirred casing from the supply and advancing the shirred length along the mandrel whilst further compressing it (e.g. to 1/50th of its original length), at the same time as a second cycle commences on the unshirred casing, (iii) further advancing the shirred casing along the mandrel, further compressing it (e.g. to 1/75th of its original length) and finally passing it to a doffing station, at the same time as a third cycle commences on the unshirred casing. Flattened cellulosic sausage casing 18 is fed through a pair of metering rollers 16 and feed rollers 19 on to a hollow mandrel 12 through which the casing is inflated. It is then shirred at 22 by three shirring rollers 10 mounted on a movable carriage S. Arm 30 is swung clear, moved to the left and re-engaged with the mandrel to grip the shirred casing at its left hand, it then moves right to slide the shirred casing along the mandrel to position 24 where it is further compressed against the stop C clamped to the mandrel; during the movement the shirred length of casing is detached from the supply. Arm 64 is then swung away from the mandrel, moved to the left and swung in to engage the rear of shirred casing 24. Clamp C is opened and arm 64 moved to the right to slide the casing along the mandrel to stop K to position 26 where it is still further compressed. Finally stop K is unclamped from the mandrel, the fully compressed casing is slid on its doffing mandrel 94 on to which it is held by arm 98, and the doffing mandrel can then be rotated through 90 degrees by a rack and pinion so that the shirred casing can be removed.
